I have a video that I need to pass on to some of my friends but it has very low audio volume.

How can I boost the audio volume in this video so that it has a similar level as my other videos? Is there a video converter that can boost the audio volume?

Check this forum. It helped me once. You will need


virtualdub (or Mod)

Lame MP3 Codec (or any other Audio Compression codec)

+1 for VirtualDub. It's a great open-source video editor. – Ben S Oct 6 '09 at 17:31

From How to increase Video Sound Levels on AVI. Files or Mpeg:

If the files are only for watching once or twice i use ONLY virtualdub, very easy.

  1. Open file in virtualdub
  2. Click on Video -> Direct Stream Copy
  3. Click Audio -> Full Processing Mode
  4. Click Audio -> Volume, then check "Adjust Volume of Audio Channels" and set the slider to for example 303%.
  5. Click File -> Save as AVI, enter a new filename and Ok.

Thats all, and you dont even have to know theres something called demux and mux. But! the file will be big as the audio is now uncompressed, not very suitable for archiving.

Edit: If its an Mpeg you need to leave Video in Full Processing Mode (unless you got a lot of harddisk space or a short video) and set a compression (i would recommend XVid) under the menu Video -> Compression. This will take quite a bit longer time btw.

This can be used in the reverse also if you need to decrease the volume of a video. – Troggy Oct 6 '09 at 19:07
